Can someone tell me where i reset the mini weather icons from the weather App?

If you want the weather app themed:

Open iFile.
Go all the way back to \
Push the hierarchy button
Search for MiniIcons
Wait a few minutes.
Open that folder
Delete everything in it
Empty Trash
Open WB
uncheck e7
Reselect e7
Respring
Open weather app.
New icons now there.

I believe there are lots of people using both with no issues. Do you have passcode turned on? That will conflict with any animations in a LS and cause your phone to kick into safe mode due to issues with RAM, from what I understand.
